2p DC 500V/600V Sup4-S40 SPD 20/40ka DC Surge Suppressors/ DC Surge Protection

 2P 500V/600V 40KA House Surge Protector Protective Low-voltage Arrester DeviceThis surge protector mainly used light volt power distribution system of lightning surge protection or other transient overvoltage. Products built for high voltage dc power supply overheating over-current protection function, can provide grade C for photovoltaic (pv) power system transient protection. Products using 35 mm DIN rail installation, module can change independently, easy to install and maintain, with remote communication alarm interface (dry contact), surge protector to facilitate remote monitoring.Technical parameters  Nominal PV System Voltage500V1000V1200VMCOV [UCPV]630Vdc1170Vdc1200VdcMax System Discharge Current (8/20 µs) [lmax]40kA40kA30kAVoltage Protection Level [UP]≤2.5kV≤4.0kV≤4.5kVVoltage Protection Level at 5kA [UP]≤2.0kV≤3.5kV≤4.0kVIntegrated Fuse Breaking Capacity/Interrupting Rating30kV/1000Vdc30kV/1000Vdc30kV/1200VdcTechnologyShort-Circuit Interruption (SCI) Overcurrent ProtectionOperating Temperature Range [TU]−40ºC to +80ºCNominal Discharge Current (8/20 µs) [(DC+/DC−)­­> PE] [In]12.5kAResponse Time [tA]
